manager favoritism?

we have a young male manager that falls all over a new employee male, the entire work place laughs behind his back, including the newer employee. New employee is not gay, manager is. Newer employee bragged about getting more hours because of the crush . The main boss passed away, while waiting for replacement GM, this young manager self appointed himself in charge and made this newer employee a supervisor. The N employee is extremely lazy, hasn't a clue of the entire operation, he only ever ran a small drink stand, much much more to learn, so to be considered a supervisor is as ridiculous as making my cat a boss. New GM comes from another state. New GM came in off season, only two people working and they did all the talking, there is NO one else to confirm or deny what these kids told him about who was in charge, they took full advantage. This Manager has pampered this guy to the point its sickening, he bends over backwards to make sure this kid doesn't have to lift a finger in fear the guy will leave, he is a college student works part time, some times part part time, making him a supervisor was just one more ploy to make him stay. is there a formal complaint I can make legally, the new GM has been brainwashed seriously. its three against one, they all know this kid is doing this but wont bring it up, they instead are sticking together as they all have their own agenda to stay relevant while pushing me , the fricking hardest working person there away. I walked away from the job as this click cannot be broken, I am livid as well as hurt at the lengths they have gone to to **** me and keep me away, a direct threat I am to there bullshit self appointed positions. I may just have to go to a higher court. its a tough call cause it looks like I am calling him out, he is not openly gay, but if this were a guy doing favors for a hot blond I wouldn't even have to be typing this right now. phewew !!
